Structure of laser sight

ABSTRACT

The present invention provides an improved structure of laser sight, which comprises a sight body, a block, a displacement adjusting device, and a switch. The block can be disposed flexibly to locations on one side of the sight body for fitting different type of firearms. The displacement adjusting device can control the location of a laser module inside the laser sight for changing the location of light emission of the laser module and modifying the location of the laser module. The switch is used for controlling the laser module and improving the convenience in control. By using the structure described above, the laser sight will have better practicability and sighting performance.

FIELD OF THE INVENTION

The present invention relates generally to an improved structure oflaser sight, and particularly to an improved structure of laser sightintegrable with various firearms and enhancing the sighting performance.

BACKGROUND OF THE INVENTION

In order to improve the shooting average of firearms, a sight, such as alaser sight, is installed at the barrel. The beam from the laser sightwill form a tiny light spot on the target. The point of impact will besurrounding the tiny light spot. Without too many influences by externalfactors such as the distance, the wind resistance, or the terrain, auser can hit the target smoothly according to the location of the tinylight spot. In particular, the value of a laser sight is apparent atnights or in the shooting environments without sufficient light.

In general, a laser sight includes a block usually formed integrallywith the laser sight or connected with the laser sight in a form hard tobe separated. On the other hand, the barrel of a firearm will include apair of grooves corresponding to the block. When the laser sight isinstalled to the barrel of the firearm, the block is wedged in thegrooves for preventing shift and loss of aim of the laser sight causedby the recoil after shooting. Nonetheless, there are various types ofguns. Due to the differences in the specifications of various firearms,the laser sight according to the prior art cannot be applied todifferent types of guns. Consequently, different guns may need separatelaser sights, leading to inconvenience in usage and an increase in cost.

In addition, as described above, external factors will influence theshooting average. It is thereby required to observe the distance of thetarget, the shooting environment, and the weather condition prior toshooting outdoors. Those external factors may result in unexpectedtrajectories and the point of impact will deviate more from the tinylight spot. Accordingly, it is required to adjust the location ofemitted light of the laser module at proper times for coinciding withthe point of impact. Nonetheless, the laser module according to theprior art is fixed inside the laser sight and the location of theemitted light cannot be adjusted. Thereby, the application is notflexible and the point of impact tends to be misjudged.

Moreover, how to enable and disable the laser module is also a veryimportant subject. For a right-handed user, when he holds the butt usinghis right hand and positions for shooting, the fingers that can be usedflexibly are the thumb and the index finger; when the left hand, as thesupporting hand, supports the bottom of the butt or the barrel, thefingers that can be used flexibly are the thumb and the index finger,too. If the power switch of the laser sight is located beyond theaccessible range of the thumbs and the index finders of both hands, theuser's action of enabling or disabling the laser sight will not befluent. According to the prior art, a wire is used for extending thepower switch outside the laser sight and disposing the power switch atthe butt. The drawback is that the power switch is located in theaccessible range of the thumb and the index finger. Once the wire ispulled, the power switch will stop functioning. Besides, disposal of thepower switch at the butt also impede the fluency of holding the gun andshooting.

Because the technologies according to the prior art cannot solve theproblem completely, breakthrough and solutions are required.Consequently, how to improve the convenience, utility, and economicalbenefits has become the critical subjects.

Accordingly, in view of the fact that the laser sights according to theprior art are unideal, the present invention provides a laser sight withmore convenience, utility, and economical benefits for promoting thedevelopment of the society.

In order to make the structure and characteristics as well as theeffectiveness of the present invention to be further understood andrecognized, the detailed description of the present invention isprovided as follows along with embodiments and accompanying figures.

First, please refer to FIGS. 1A, 1B, and 2, which show exploded views(1), (2) and a top view of the structure according to the firstembodiment of the present invention. As shown in the figures, thepresent embodiment comprises a sight body 10, a block 30, and aplurality of fixing members 35. The sight body 10 has a clamping track12 and two positioning trenches 14 on one side. The two positioningtrenches 14 are disposed between two guiders 122 of the clamping track12. Besides, there is a spacing 16 between the two positioning trenches14 adjustable according to the type of firearms. The block 30 isdisposed at the positioning trench 14. The plurality of fixing members35 are fixed and locked in the positioning trenches 14 and position theblock 30 in the positioning trench 14.

Please refer to FIG. 3, which shows an internal schematic diagramaccording to the first embodiment of the present invention. As shown inthe figure, the clamping track 12 includes two guiders 122 and anelastic device 124. The two guiders 122 are opposing to each other anddisposed on one side of the sight body 10. The elastic device 124 isdisposed inside the sight body 10 and connected with the two guiders122. The barrel of a firearm is loaded between the two guiders 122. Thebarrel has a groove (not shown in the figure) corresponding to the block30. The block 30 is wedged and matched in the groove. When the barrel isdisposed at the sight body 10, the clamping track 12 and the block 30provide the positioning function for preventing shift of the sight body10 due to the recoil of shooting.

Please refer to FIG. 4, which shows a schematic diagram of the sightbody assembled with a firearm according to the first embodiment of thepresent invention. As shown in the figure, the present embodimentfurther comprises a positioning block 18 disposed in the positioningtrench 14. The plurality of fixing members 35 fix and lock thepositioning member 18 in the positioning trench 14 for filling thepositioning trench 14. The positioning block 18 is disposed in thepositioning trench 14 different from the one for the block 30. Theplurality of fixing members 35 fix and lock the block 30 and thepositioning block 18 in the plurality of positioning trenches 14 in adetachable method. Thereby, for changing the block 30 to the otherpositioning trench 14, after releasing the fixing member 35 fixing andlocking the block 30, the block 30 can be separated from the above ofthe positioning block 18. Then the same method is applied for releasingthe positioning block 18 in the other positioning trench 14 andexchanging the positioning trenches 14 for the block 30 and thepositioning block 18. Afterwards, the fixing members 35 are used forfixing and locking the block 30 and the positioning block 18,respectively, and completing the exchange. Accordingly, a user canadjust the disposition of the block 30 to any positioning trench 14according to the locations of the trenches on a firearm. Alternatively,two blocks 30 can be disposed in the positioning trench 14 concurrentlyso that the sight body 10 can be applicable to any type of firearm.

Please refer to FIG. 5, which shows a cross-sectional view of thestructure according to the first embodiment of the present invention. Asshown in the figure, the sight body 10 has a heat sink 102 therein. Theheat sink 102 is connected with a laser module 20. One end of the heatsink 102 passes through a heat dissipation tunnel 104 of the sight body10. One end of the heat sink 102 is parallel with or lower than a heatdissipation hole 106 of the heat dissipation tunnel 104, so that theheat generated by the laser module 20 can be conducted to the heat sink102 and further dissipated through the heat dissipation hole 106. Theheat dissipation tunnel 104 and the heat dissipation hole 106 can belocated on any side of the sight body 10. According to the presentembodiment, the heat dissipation tunnel 104 and the heat dissipationhole 106 are disposed on the same side of the block 30. After the sightbody 10 is assembled with a firearm, the heat dissipation hole 106 canbe covered up, and hence avoiding moisture and foreign matters fromentering the sight body 10 via the heat dissipation hole 106. Besides,the appearance will be pleasing to the eye.

Please refer to FIG. 6 and FIG. 7, which show an external view and aninternal view of the structure according to the second embodiment of thepresent invention. As shown in the figure, the present embodimentcomprises a sight body 10, a first adjuster 50, a first displacementdetector 55, a second adjuster 60, and a second displacement detector65. The sight body 10 has a laser module 20 therein. The first adjuster50 includes a first knob 502, a first push member 504, and a firstelastic member 506. The first knob 502 is disposed on one side of thesight body 10. The first knob 502 has a plurality of scale grooves 5021on one side. The first push member 504 is disposed inside the sight body10. One end of the first push member 504 is connected with the firstknob 502 while the other end thereof is disposed against the lasermodule 20. The first elastic member 506 corresponds to the first pushmember 504 and is disposed on one side of the laser module 20. The firstdisplacement detector 55 includes a first elastic base 552 and a firstpositioning shaft 554. The first positioning shaft 554 is dispose on thefirst elastic base 552. One end of the first positioning shaft 554corresponds to the plurality of scale grooves 5021 of the first knob502. The second adjuster 60 includes a second knob 602, a second pushmember 604, and a second elastic member 606. The second knob 602 isdisposed on one side of the sight body 10. The second knob 602 has aplurality of scale grooves 6021 on one side. The second push member 604is disposed inside the sight body 10. One end of the second push member604 is connected with the second knob 602 while the other end thereof isdisposed against the laser module 20. The second elastic member 606corresponds to the second push member 604 and is disposed on one side ofthe laser module 20. The second displacement detector 65 includes asecond elastic base 652 and a second positioning shaft. The secondpositioning shaft is disposed on the second elastic base 652. One end ofthe second positioning shaft corresponds to the plurality of scalegrooves 6021 of the second knob 602.

The first push member 504 of the first adjuster 50 has a thread segmenton the surface. By turning the first knob 502, the first push member 504is moved towards the inside or outside of the sight body 10. If thefirst push member 504 is move towards to inside of the sight body 10,the first push member 504 will push the laser module 20 and make theemitted light of the laser module 20 move. Besides, the first elasticmember 506 on one side of the laser module 20 will be pressed andforming a buffer. On the other hand, when the first push member 504 ismove towards to outside of the sight body 10, due to the elastic forceof the first elastic member 506, the laser module 20 will move towardsthe direction of the first push member 504. The principle by which thesecond knob 602, the second push member 604, and the second elasticmember 606 of the second adjuster 60 move the laser module 20 is thesame as the one described above. Hence, the details will not bedescribed again.

The first positioning shaft 554 has a first sphere 5541 at one end. Thefirst sphere 5541 will contact the scale groove 5021 of the first knob502 under the elastic force of the first elastic base 552. When thefirst knob 502 is turned, because the first sphere 5541 has a curvedsurface and bears the rotational force from the first knob 502, thefirst sphere 5541 will slide out of the scale groove 5021 and intoanother scale groove 5021. In other words, the laser module 20 moves byone scale. This action will generate a jump or a sound, which remindsthe user of the distance by which the laser module 20 has traveled. Theoperating method and effect of the second displacement detector 65 isthe same as those of the first displacement detector 55. Theirdifference is only on the accompanying adjusters. Hence, the detailswill not be described again.

The first adjuster 50 and the second adjuster 60 are perpendicular toeach other. The first adjuster 50 is disposed on the right side of thelaser module 20 and enables the laser module 20 to move in the Xdirection. The second adjuster 60 is disposed on the bottom side of thelaser module 20 and enables the laser module 20 to move in the Ydirection.

Please refer again to FIG. 7. The present embodiment further comprises acorrection kit 100 located among the first adjuster 50, the secondadjuster 60, and the laser module 20 and put around the outer side ofthe laser module 20. Because the light emitted by the laser module 20may have shift, the correction kit 100 disposed on the outer side of thelaser module 20 can adjust the angle in advance. Consequently, the beamof the laser module 20 can be emitted at a normal angle.

Please refer to FIG. 8, FIG. 9, and FIG. 10, which show an exploded viewand functional diagrams (1), (2) of the switch according to the thirdembodiment of the present invention. As shown in the figures, thepresent embodiment comprises a sight body 10 and a switch 70. The sightbody 10 has a circuit module 90 therein. The circuit module 90 includesa circuit board 92 and a conductive member 94. The circuit board 92 isconnected electrically with a laser module (not shown in the figures);the conductive member 94 is connected electrically with the circuitboard 92. The switch 70 includes two handles 72, a link 74, a conductivepart 76, and a unidirectional torque spring 78. The two handles 72 aredisposed on both sides of the sight body 10, respectively. The link 74is disposed pivotally inside the sight body 10 with both ends connectedwith the two handles 72, respectively. The conductive part 76 isdisposed at the link 74 and corresponding to the conductive member 94.The conductive part 76 and the link 76 can be formed integrally.Alternatively, the conductive part 76 contacts the link 74 and isdisposed at the link 74. The unidirectional torque spring 78 is disposedat the link 74. One end of the unidirectional torque spring 78 isconnected electrically with the circuit board 92.

The switch 70 is used for activating or deactivating the laser module20. In FIG. 9, the deactivated state is shown. The link 74 is turned bypushing the handle 72. As shown in FIG. 10, the two handles 72 areturned downwards by approximately 15˜60 degrees for driving theconductive part 76 to rotate, which enables one side of the conductivepart 76 to contact the conductive member 94 and thus shorting thecircuit to the circuit board 92 and activating or deactivating the lasermodule 20. When the handles 72 are released, the link 74 will restorethe handles 72 to their original positions using the elastic force ofthe unidirectional torque spring 78. Meanwhile, the conductive part 76will rotate in the reverse direction to the original position andrelease the contact with the conductive member 94. Thereby, activationand deactivation of the laser module 20 can be performed. The conductivemember 94 is a positive terminal while the unidirectional torque spring78 is a negative terminal. A wire 96 is used for connecting theconductive member 94 and the unidirectional torque spring 78 to thecircuit board 92, respectively.

The two handles 72 according to the present embodiment are disposed onboth sides of the sight body 10 and close to the active range of theuser's thumb and index finger. In addition, the two handles 72 areinterlocked with the link 74. The two handles 72 can be controlledfluently regardless whether the dominant hand is used. For differenttypes of firearms, the supporting hand can also control the two handles72 with ease from the location where it rests. Accordingly, the fluencyin usage is enhanced.

Please refer again to FIG. 2. The present embodiment can furthercomprises an indicator 110 disposed on one side of the sight body 10 andconnected electrically with the circuit board 92. When the state of theswitch 70 is switched, the indicator 110 will be turned on or off. Thepreferred location for disposing the indicator 110 is the rear side ofthe sight body 10. Because the rear side is closer to the user, it willbe more convenient for viewing. Besides, the location is hard to befound by a nonuser. Thereby, the location of the user will be exposedeasily.

Please refer to FIG. 11, which shows a schematic diagram of thefrequency adjuster according to the third embodiment of the presentinvention. As shown in the figure, the circuit board 92 is furtherconnected electrically with a frequency adjuster 80. The frequencyadjuster 80 is disposed on one side of the sight body 10 and connectedelectrically with the circuit board 92. Then a lid 82 is used forsealing. The lid 82 is screwed to the sight body 10. In addition, awaterproof washer can be further disposed between the lid 82 and thesight body 10 for improving water resistance. The frequency adjuster 80is used for adjusting the frequency of light emission of the lasermodule 20, for example, continuous illumination or cyclic illuminationof 3-second emitting and 2-second not emitting. After selecting thefrequency, the laser module 20 is activated by the switch 70. Thereby,the practicability and the flexibility in tactical application can beenhanced.

To sum up, the laser sight according to the present invention can bedisposed to any positioning trench via the block and thus applicable toa variety of firearms. In addition, by adjusting the location of thelaser module using the adjusters for different axes, the emitted lightspot of the laser sight can be modified to coincide with the point ofimpact and increasing the shooting average. Then the switch is used forcontrolling the laser module, and hence improving the fluency of usageand getting close to users' operating ranges and usage conditions.Thereby, the flexibility and shooting accuracy of the laser sight can beimproved.
